[Elecraft] Kat500 Firmware

[Richard Gilley]

Hi,
	Having difficulty loading latest version of the Kat500 utility.  The version I have is 01.75, the utility indicates that 2.05 is available.  However the new version does not load but the message “ Input hex file is corrupt, check sum is not zero”

I have the same issue attempting to load a Mac and Linux.

Perhaps 2.05 is not available?  Or is there a fix I am not aware of, or perhaps it is not necessary to upgrade?

Thank you for your interest. Help would be appreciated.

Best
